I've recently upgraded to macOS 13 (Ventura) and EOS Webcam Utility doesn't work anymore. I tried both amd64 (EOS Webcam Utility 1.0) and arm64 (EOS Webcam Utility 1.1) versions, but none of them work properly.
EOS Webcam Utility 1.0 freezes, and EOS Webcam Utility 1.1 only works once after a system restart when camera is turned on and off a couple of times, but then system loses the connection with the device.
Please publish a fix of the software as soon as possible for your customers like me who are depending on the camera for their day to day work.
I'm on the same situation, and I've got to admit it was my fault for not checking first if there was any other people impacted before to upgrade. Because there was already. You just need to take a quick look here in the Community.
While we wait for an update of EOS WebCam Utility certified for macOS Ventura, I recommend you, in the case you have an iPhone on iOS 16.1, to use it as webcam.
This is a new feature that works OOTB on macOS Ventura and iOS 16, and what saved my life since I upgraded, on Oct 27th. It works great even wireless, but better use it wired.
If you use an Android instead, you can use Camo app (free version), which works the same way.
Hopefully an upgrade will come in not so much time, but at least that way you will be able to use a quality camera for your WebCam requirements in the short term.
Wait is over.
Go to Canon US download site, select your camera model, select macOS 12 (I know that Ventura is macOS 13, but the relevant version of Webcam Utility is available when you select 12 instead of 13).
Download and install EOS Webcam Utility Pro 2.0 (macOS)
After a reboot, my EOS camera is working again with Teams and so thru USB on macOS Ventura.
Hope it can be helpful,
It's a long process but, backup your computer to Time Machine, reset your computer on System Settings, reinstall EOS Utility from the Japanese Canon site (translate to English), and it should work on Ventura. A community member genius suggested getting the getting the Utility directly from the Japanese Canon site. Very smart.
You have to uninstall the previous version of Canon webcam utility first.
Here's how to uninstall Canon's webcam plug-in. This won't have any affect on EOS Utility other than to disable the webcam functionality.
Go to the Finder.
From the Go menu on the menubar, choose Computer.
Navigate to the folders: Library ➟ CoreMediaIO ➟ Plug-Ins ➟ DAL
Find the file called EOSWebcam.plugin
5. Drag this plug-in to the Trash, or pick Move to Trash for the File menu.
6. You will be prompted to enter your computer password or fingerprint.
After doing that, you may install the new version of Canon Webcam utility Pro.
Restart your mac.
Remember that version requires you initiate the app to use your canon as a webcam, so before open you stream software (zoom, obs, etc), you may have to initiate the EOS WEBCAM app.
You don't need to manually uninstall the utility files like that, each version of utility has it's own uninstaller, which is in the Applications folder under EOS Webcam Utility folder.
I've tried uninstalling the older version - I do that every time when I try another version. But it doesn't help, the discussed pro version (2.0) doesn't work at all for me. The only version that works half measure is the 1.1 version, then I need to restart my camera device and toggle camera view in meeting softwares for some time until it starts to work on a single stream. The same goes every time a share my cam, it's pretty annoying.
OK, I solved my problem of the installation failed. I was saving it to dropbox, with on the M1 is in 'cloud storage', which has been causing a bunch of problems, even when the files are marked 'make available offline'.
solution: moved the installation file to the local, specifically the desktop, installed perfectly.
